Suggestions PLEASE! I Want to HELP TOO!

Okay, here's the story:

Setting:
We have a non-profit organization that has been formed by several family members about 3 years ago. The non-profit organization has one annual event that raises money for cancer research. Everyone (family members and friends) is somewhat involved. However, the family members and friends are involved if we go by what this one person wants. She likes to control of what goes on. She is president of the organization. Everyone else just contributes their time and money. There use to be a committee for the organization, but it dissolved because the president didn't keep in touch with anyone over the year regarding the setup and plans of the annual event. She wants people to help, but only if we do it her way. The president of this organization insists on doing everything her way...even if it doesn't look good or doesn't have common sense. This non-profit organization has a lot of elements that need help and she wants to do it all herself, her way, period.

To keep a organization going, it takes a lot of time and two people doing the whole organization is not enough.

Problem:
The organization recently sent a newsletter to all its supporters. I am sorry to say this, but I wasn't impressed. A lot of us that are supporters of this organization were not impressed with the newsletter. It had a lot misspelled words, not organized newsletter format, and not-so-good sentence structure. It wasn't a good newsletter. It was sloppy, it looked like the person who did this newsletter did not take the time and dedication to make it look presentable and enthusiatic about the newsletter. I am not being hard on anyone. I took the contents and made up another newsletter and gave it to people outside the organization because we were kind of embarrassed with the newsletter that we received from the president and her mom.

What I want to do is show them that I would like to help them out and show them the newsletter that I did to give to our friends that haven't seen either newsletter. I don't want to get them angry, I want to say to them "I want to help. This is what I did to the Newsletter. Can I help out with your newsletter?" Do you think that would be a bad thing? Do you think that I can approach them without making them angry or make them hate me?

Point is is that I want to help make this organization newsletter pop out! I want to contribute my time and talent to attract people more to this organization and want to be a part of the annual event to raise money for cancer research. I want to volunteer...but how do I do that when they think they don't need help or they think that what the newsletter looks fine! Thank you A2K family!
